Scientists around the world believe that after the Big Bang, the Universe has come into existence. At that time it was not so huge as it is in the present time. It was hot and dense and was growing rapidly. After 13.8 billion years, we now know what it looks like. However, how exactly this hot and dense material cooled still remained a puzzle for scientists. Scientists have been trying to understand for over 20 years what exactly happened in the first microsecond of Bing Bang before the birth of the universe? Now scientists have found the answer to what the hot dense substance was like and how it changed.
The scientists studied data from an experiment conducted by the Large Hadron Collider at the European Organization for Nuclear Research (CERN). In the experiment, he created the hot and dense matter present in the early stages of the universe. Scientists at the University of Copenhagen found that the experiment’s data was accurate enough to conclude that the initial substance was in the form of a flowing liquid.
This was the initial substance of the universe
This substance can be separated because it keeps changing its shape over time. The only hot and dense matter that existed in the early stages of the universe was made up of quarks and gluons. It is also known as Quark-Gluon Plasma (QGP). A quark is a fundamental particle, which combines together to form protons and neutrons. The gluons act as a binding material, like glue, that holds the quarks together.
What is the function of quarks and gluons?
Yu Zhou, an associate professor at the University of Copenhagen and one of the authors of this study, said, the first quark and gluons plasma was separated from the hot expanse of the universe. Then the quark fragments turned into hadrons. A hadron consisting of three quarks forms a proton, which is part of the atomic core. These are the core building blocks that make up the Earth, us and the universe around us. The study will be published in the July issue of Physics Letters B.
What is the Big Bang Theory?
The Big Bang is a scientific theory of the creation of the universe, which gives answers as to when and how the universe formed. According to this theory, about 15 billion years ago, all physical elements and energy were confined to a single point. What was there before, no one knows about this. Then this point started spreading. The Big Bang was not a bomb-like explosion, but rather the particles of the early universe spread throughout space and ran away from each other. It is believed that the universe has been continuously expanding since then.
